Today: the five AI headlines of the day → and the AI Wiki
What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-SG-2026-018 · Evidence B · P1

The gamified mHealth arm also showed eight-week between-group improvements of 0.54 kg in skeletal muscle, 0.46 percentage points in body-fat reduction, 6.5 seconds in run time and 2 points in depressive-symptom reduction, while body weight and BMI differences were not significant.

What this does not establish

Selected short-term secondary changes are not clinical remission, durable mental-health benefit, weight-loss efficacy or effects of gamification alone.

Counterevidence & uncertainty

Diet and sleep were not systematically controlled; multiple secondary outcomes raise multiplicity concerns.

What would change the reading

Update with corrected multiplicity, objective replication and follow-up after incentives stop.
